  1. I did a reprocess of the image and got about 10 minutes more exposure. The image is less noisy but have lost any colour! M051 - Whirlpool Galaxy by ejwwest, on Flickr
  2. About 55 minutes of exposure with a mix of 5 mins at 800 and 1600 ISO and 1 minute shots at 1600 and 3200 ISO. Stacked with DeepSkyStacker M51 - The Whirlpool Galaxy by ejwwest, on Flickr
  3. Seen last night over Hampshire: ISS and Dragon Supply Craft by ejwwest, on Flickr The Dragon supply ship is the fainter track below the much brighter ISS track
  4. Another shot from last night: Jupiter with Red Spot and Shadow of Io by ejwwest, on Flickr
  5. This photo is published in the Gallery of the June 2015 edition of Sky and Telescope. My complimentary copies arrived today. Should be on general release in a week or so. Sent from my iPad using Tapatalk
  6. If anyone has recommended Registax wavelet settings and/or capture settings for a DFK21AU618 I would appreciate it.
  7. Seeing not very good tonight but will try some reprocessing of the images. DFK21AU618 at prime focus of EdgeHD 925 scope with 2x Barlow. Pre-processed with PIPP to select best 2000 frames, stacked with AS2, sharpened with Registax 6 and finished in PSE 12. Jupiter with Great Red Spot and Shadow Transit of Io by ejwwest, on Flickr and earlier shot without the transit and not processed in PSE12: Jupiter and red spot by ejwwest, on Flickr
  8. Over Chandlers Ford, Hampshire International Space Station and Iridium Flare by ejwwest, on Flickr
  9. Taken with my DFK21AU618 Jupiter with Shadow of Ganymede by ejwwest, on Flickr Jupiter with Shadow of Ganymede by ejwwest, on Flickr
  10. One of my photos of Baily's beads from this eclipse are being used on the BBC's iWonder site for Stargazing Live this week: http://www.bbc.co.uk/guides/zcytpv4
  11. Trying to decide between Oregon (less chance of cloud cover) or South Carolina (not been before and historical sights to compensate if the skies are cloudy). Yellowstone is likely to be popular and not much chance of getting accommodation within close driving distance to the path of totality.
  12. I did consider going to Torshavn but decided that if it were clouded out that there would be few compensating activities so went on a Northern Lights photography trip to Iceland where we were clouded out most of the week but got great glacier and ice photos instead. My next eclipse is the USA in 2017. Just need to decide where to view it! Good luck on Friday.
  13. I've been meaning to prepare this since 2008 from my photos of the total eclipse in the Gobi Desert in China and the partial eclipse this week spurred me on to do so. The equipment was a Canon 40D with a 100-400mm zoom lens and 1.4x extender (560mm focal length). During the partial phases a Thousand Oaks filter was used.

  14. A slightly modified version of the above. The photomerge to get a full Gibbous moon meant the ISS on the edge of the Moon was inadvertently removed (comes of doing this at 1230 am!).
  15. Yes, I used my Canon 70D - pretty high frame rate (7 fps) and could set a high ISO to get the shutter speed fast enough. Use Calsky.org to see when the next one is near you. They probably occur at any site a couple of times a year (or there will be ones within 20 miles more frequently) but the ideal circumstances seem to be less frequent.
  16. Best place to check these is Calsky.org but also double check with heavens-above.com as I have had unsuccessful attempts when these disagree. They do not come frequently and needs the right set of circumstances. I just about got near perfect seeing, focus (though collimation probably needs adjusting), exposure and timing.
  17. Taken at prime focus of Celestron EdgeHD 925: Sequence of the ISS Transiting the Moon by ejwwest, on Flickr
  18. Quite hazy viewing: In 50mm lens: Comet 2014 Q2 Lovejoy by ejwwest, on Flickr And 400mm: Comet 2014 Q2 Lovejoy by ejwwest, on Flickr
  19. These were 2 second subs. Unguided that's about the limit with this lens to avoid star trailing. I pushed the ISO to 6400. Sent from my iPad using Tapatalk
  20. Single frame. Am processing a stack with DSS but for some reason it loses the colour! Will post that when I fix it.
